[0002] Although the structure of the mold may vary due to the variety and performance of the plastic, the shape and structure of the plastic product, and the type of the injection machine, the basic structure is the same. During the continuous processing of the injection mold, the injection material is continuously heated. As the temperature rises, due to poor heat dissipation, it is easy to cause slow molding of the product, prolonging the demoulding time, and deformation of the product during the demoulding process, resulting in scrap. If the cooling water is passed through for a long time, the injection plastic in the mold will be deformed due to soaking in the cooling water, which will make the injection plastic scrap and increase the production cost

The invention discloses a cooling device used for a plastic injection mold. The cooling device comprises a shell. A cylinder body is mounted in the upper surface of the shell in an inlaid mode. Firstthrough holes are formed in the surface of the cylinder body. The upper portion of the surface of the cylinder body is sleeved with an upper cover. A deflation device is fixedly mounted on the right side of the bottom surface of an inner cavity of the shell. A rotary rod is rotatably mounted on the right side of the top surface of the inner cavity of the shell. The upper portion of the surface ofthe rotary rod is fixedly sleeved with a rotary disc. A through hole is formed in the right side of the upper surface of the rotary disc. A fixing pipe closely attached to the rotary disc is mounted in the middle of the upper surface of the shell in an inlaid mode. The upper end of the rotary rod penetrates through the top surface of the inner cavity of the shell to extend into the inner cavity. Astorage tank, the rotary disc, a first gear and a second gear are additionally arranged on the cylinder body, so that the deflation device is driven by the rotary rod to intermittently release liquidnitrogen stored in the storage tank into the shell; and the mold and injection molding materials in the cylinder body are intermittently cooled by a refrigerant, so that deformation, caused by watersoaking, of the mold is avoided.
Description
technical field [0001] The invention relates to the technical field, in particular to a cooling device for a plastic injection mold. Background technique [0002] Although the structure of the mold may vary due to the variety and performance of the plastic, the shape and structure of the plastic product, and the type of the injection machine, the basic structure is the same. During the continuous processing of the injection mold, the injection material is continuously heated. As the temperature rises, due to poor heat dissipation, it is easy to cause slow molding of the product, prolonging the demoulding time, and deformation of the product during the demoulding process, resulting in scrap. If the cooling water is passed through for a long time, the injection plastic in the mold will be deformed due to the cooling water immersion, which will make the injection plastic scrap and increase the production cost.
